Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header, 4 Contacts, 3 mm Pitch, 2 Row, Shrouded 43045-0412

Molex 43045-0412 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a durable and compact connector solution designed to provide reliable wire-to-board electrical connections. Featuring 4 male contacts in a 2-row shrouded format with a 3 mm pitch, this header accommodates up to 5 Amps current per pin, making it suitable for low to mid-range power distribution applications.

Constructed with a high-temperature thermoplastic housing, this PCB header withstands infrared reflow soldering temperatures up to 265°C, suitable for modern manufacturing environments. The contact system utilizes tin-plated brass for superior electrical conductivity and corrosion resistance, which ensures long-lasting performance in demanding industrial conditions.

The header design includes fully isolated dual-beam terminals for secure contact and consistent electrical performance. Additionally, polarised pins prevent misaligned or mismatched connections, minimizing the risk of short circuits or component damage during assembly or service. Kinked solder legs provide enhanced PCB retention during soldering processes, further strengthening the mechanical connection.

This 43045-0412 header is ideal for use in gaming consoles, solar power setups, medical devices, and complex data/telecommunications networks where dependable power connection is critical.
